3.0 Network Conguration
3.2 Establishing IP Connectivity
The DSM3 Series supports the CableLabs DOCSIS 2.0+IPv6 implementation. The main benet of
IPv6 is its expanded addressing capability, increasing the address space from 32 to 128 bits, providing
virtually unlimited number of networks and systems. The DSM3 Series determines the IP provisioning
mode via the CableLabs SNMP MIB parameter docsIf3CmMdCfgIpProvMode (SNMP OID: 1.3.6.1.4.1
.4491.2.1.20.1.31.1.1). The DSM3 Series will support the following congurable IP Provisioning Mode
Override policies:
• Honor MDD: The cable modem of the DSM3 Series unit will acquire an IPv6 or IPv4 address as
directed by the MAC Domain Descriptor (MDD) message for provisioning and operation.
• IPv4 only: The cable modem of the DSM3 Series unit will acquire a single IPv4 address for the CM
management stack, overriding the TLVs in the MDD message.
• IPv6 only: The cable modem of the DSM3 Series unit will acquire a single IPv6 address for the CM
management stack, overriding the TLVs in the MDD message.
3.3 The DOCSIS Conguration File
A cable modem’s DOCSIS Conguration File is a type-length-value (TLV) le that contains important
operational parameters as dened by the DOCSIS standards. It provides certain settings for the cable
modem. In addition to standard entries, settings in the DOCSIS Conguration File should include the
modem’s community strings and if an upgrade is necessary, rmware upgrade parameters. Place the
Conguration File in the TFTP root directory.
The DSM3 Series cable modem interface can support both IPv4 and IPv6 addressing schemes. The
required DOCSIS Conguration File operational parameters will differ depending on company policies,
cable modem rmware versions and IP addressing schemes. The following DOCSIS Conguration File
details listed in this manual are general guidelines. Please consult the published DOCSIS Specication
resources (CableLabs) for additional DOCSIS Conguration File details and guidelines.
To build a DOCSIS Conguration File, use a DOCSIS TLV editor program.
See the example Conguration Files in Sections 3.3.5 and 3.3.6.
3.3.1 Setting Modem Community Strings — DOCSIS 2.0 (IPv4) Method
Set the modem community strings with the DOCSIS Conguration File by including the following
SNMP parameters:
The modem community strings should be set in the DOCSIS Conguration File. Failure to set community strings
will result in a less secure system. For automatically updating modem rmware with the DOCSIS Conguration File,
see Section 5.1, Upgrading DSM3 Series Modem Firmware.
NOTE:
MIB Parameter Object ID Description Value
docsDevNmAccessIp 1.3.6.1.2.1.69.1.2.1.2.x The IP address (or subnet) of the network
management station
e.g. 10.20.30.0
docsDevNmAccessIpMask 1.3.6.1.2.1.69.1.2.1.3.x The IP subnet mask of the network
management stations
e.g. 255.255.255.0
docsDevNmAccessCommunity 1.3.6.1.2.1.69.1.2.1.4.x The community string matched to this IP
address net mask entry
alphanumeric string
docsDevNmAccessControl 1.3.6.1.2.1.69.1.2.1.5.x The level of access granted 1= none
2= read only
3= read/write
docsDevNmAccessInterfaces 1.3.6.1.2.1.69.1.2.1.6.x Species the set of interfaces from which
requests from this NMS will be accepted
0x40 : Cable interface (typical)
0x80 : Ethernet interface
0xC0 or 0x00 : Both interfaces
docsDevNmAccessStatus 1.3.6.1.2.1.69.1.2.1.7.x Controls and reects the status of rows in
this table
